if have generic ienumerable<int>. can apply tolist() or toarray() or firstordefault() it. how apply these methods non-generic ienumerable?

you have couple of options:

1. if know objects in enumerable of same type, can cast generic ienumerable<yourtype>. in worst case can use object:

   object first = enumerable.cast<object>().first(); 

2. or can use enumerator, make 1 step , take current element:

   ienumerator enumerator = enumerable.getenumerator(); enumerator.movenext(); object first = enumerator.current;
